Startup Deep Dive : Salesken — an AI sales coach built by the trainer who used to do it by hand

Salesken raised more than $30 million from backers including Sequoia India and Microsoft’s venture arm, M12, to build an AI that coaches sales reps while they are still on the phone. Then its own revenue fell by roughly half in a single year: ₹5.1 crore ($0.53 million) in FY25, down 49.1% from ₹10.0 crore ($1.0 million) the year before, as per the company’s financial filings tracked by Inc42.

That drop sits oddly next to the founding story. Co-founder Surga Thilakan did not start out selling software. Before Salesken, she spent years running a sales-training business that coached more than 20,000 representatives from low-income backgrounds, face to face, one call at a time. Salesken automates the job she once did in person: real-time prompts fed to a rep mid-call, not a review the following week. What happened between that ambition and the FY25 numbers is the rest of this piece.

Quick facts

What Salesken actually sells

Salesken sells an AI-based conversation-intelligence and real-time coaching platform to business-to-business sales organisations. The product listens to a sales call as it happens, over voice or video, and uses speech analytics to flag script deviations, missed objection-handling moments and talk-to-listen ratios while the rep is still on the line, rather than in a quality-check review days later. Its buyers are enterprise and mid-market sales operations that run high call volumes: inside-sales desks, financial-services and insurance telecalling teams, SaaS sales floors and outsourced sales operations — broadly the same segment Thilakan spent a decade training in person before the company automated the coaching itself.

The origin

Before there was a line of code, there was a classroom. Surga Thilakan worked as an investment banker at Goldman Sachs in London before returning to India to start a skills-training operation. That business, incorporated as iStar Skill Development Private Limited on 8 December 2009 and co-founded with Sreeraman Vaidyanathan, trained more than 300,000 students and, within that, over 20,000 sales representatives drawn largely from low-income backgrounds, teaching them how to hold a sales conversation and close it.

The insight that became Salesken was simple and hard-won: the difference between a rep who converts and one who does not is rarely product knowledge, it is what they say and do not say in the first ninety seconds of a call, and whether someone corrects them while the conversation is still live. Thilakan and Vaidyanathan had spent years doing that correction by hand, one trainee at a time. Salesken’s pitch is that the same correction can be delivered by software, to every rep, on every call, at once — a real-time coach standing in for the trainer who cannot be on every line simultaneously.

The struggle years

The company’s own history undercuts the tidy version of its founding date. Funding announcements around the November 2021 Series B round describe Salesken as “founded in 2018,” yet the legal entity behind the product, iStar Skill Development, had already been operating as a human-delivered training business for nine years by then. Read plainly, that gap is itself the first setback: a services business that took most of a decade to become confident enough in its own methodology to encode it as a product, rather than a startup that arrived at its idea on day one.

The more recent struggle is starker and better documented. Salesken’s revenue nearly halved in FY25, falling to ₹5.1 crore from ₹10.0 crore in FY24, a 49.1% year-on-year decline, according to its financial filings as tracked by Inc42. That contraction did not come with lower spending to match: total expenses in FY25 stood at ₹22.2 crore against revenue of ₹5.1 crore, and the net loss widened to between ₹17.2 crore and ₹17.4 crore for the year. Company filings tracked separately by Tofler show the entity’s book net worth had already fallen 36.5% in FY23 even as revenue grew 31.6% that year — a business that was burning capital to fund growth well before the FY25 slide. Headcount data tracked by PitchBook shows a fall from a peak of around 116 employees to roughly 82-88 more recently, consistent with a company that scaled down after the revenue contraction rather than through it.

The turning point

If there is a single hinge in Salesken’s history, it is 22 November 2021. Until then, the company had raised a modest $3.6 million seed round in December 2018 from the Michael & Susan Dell Foundation and Unitus Ventures, followed by an $8 million Series A in March 2020 led by Sequoia India — in which the seed investors partially exited, as reported at the time by YourStory, Inc42 and Business Insider India. Cumulative funding stood at roughly $11.6 million, and the business was still overwhelmingly an India story.

Then M12, Microsoft’s venture fund, led a $22 million Series B alongside existing backer Sequoia India, taking cumulative funding to more than $33 million. M12 partner Abhi Kumar joined Salesken’s board, and the company said explicitly, in its own announcement carried by PRNewswire, that the capital was meant “to expand in US market.” A domestic sales-training-turned-software company had, on paper, become a Microsoft-backed platform with a mandate to compete in North America. What came after that mandate — a revenue base that shrank rather than grew over the following fiscal years — is the tension this piece keeps returning to.

The money behind it

• Seed — December 2018: $3.6 million from the Michael & Susan Dell Foundation and Unitus Ventures (Tracxn funding data).
• Series A — 5 March 2020: $8 million led by Sequoia India, with Michael & Susan Dell Foundation and Unitus Ventures partially exiting in the same round (YourStory, March 2020; Inc42, March 2020; Business Insider India, March 2020).
• Series B — 22 November 2021: $22 million led by M12 (Microsoft’s venture fund), with Sequoia India participating; M12 partner Abhi Kumar joined the board (BusinessToday, November 2021; Entrackr, November 2021; PRNewswire, November 2021).
• Venture debt — July 2022 and March 2023: $9.7 million from InnoVen Capital (July 2022) and $3.2 million from Stride Ventures (March 2023), per Tracxn’s funding record — debt rather than priced equity, and the only capital raised after the 2021 Series B.
• Total raised: reported as $30 million (Inc42), $31.8 million (PitchBook) or $33 million (CBInsights, YourStory) across sources — the figures cluster around $30-33 million and no source disputes the underlying round list, only the running total.
• Latest valuation: not publicly disclosed. No priced equity round has been announced since the November 2021 Series B.
• Board influence: Sequoia India / Peak XV Partners holds a board seat through partner Shailesh Lakhani, named as a director of iStar Skill Development in company-registry filings (Tofler, ZaubaCorp); M12’s Abhi Kumar joined after the Series B.

How it makes money

Salesken is a subscription software business sold into sales and revenue-operations teams, priced by seat or licence in the way most conversation-intelligence tools in its category are sold; the company has not published a per-seat price list, so that figure is left out here rather than estimated.

• Money in: recurring enterprise SaaS contracts with sales organisations that run high call volumes — the buyer is typically sales operations or a chief revenue officer, not an individual rep (company product description, PRNewswire and BusinessToday funding announcements).
• Costs out: speech-to-text transcription and NLP inference running on cloud infrastructure, plus an India-based engineering and customer-success team. FY25 filings show total expenses of ₹22.2 crore against revenue of ₹5.1 crore — a cost base more than four times the year’s revenue (Inc42, MCA-sourced financials).
• Where the margin sits: in theory, in software gross margin once a customer is live and the model is tuned to their script and product vocabulary; in practice, the FY25 filings show a company still spending far ahead of what it collects, with no disclosed path to breakeven in public filings.
• The part people get wrong: Salesken is marketed as a coaching tool, but its own founding description — standardising what a good call sounds like across hundreds of reps rather than motivating any one individual — points to something closer to a compliance and quality-assurance layer sold with a coaching label attached.

The numbers

Public, sourced figures are available only for the two most recent fiscal years plus a directional data point for FY23; absolute FY22 and FY23 revenue and profit figures sit behind paywalled registry data and are not included here rather than estimated.

• FY23: revenue grew 31.6% year-on-year while book net worth fell 36.5%, implying losses were already being funded by capital rather than operations (Tofler, sourced from MCA filings).
• FY24: revenue of ₹10.0 crore ($1.0 million), the high point in the two years for which absolute figures are public (Inc42).
• FY25: revenue fell to ₹5.1 crore, expenses were ₹22.2 crore, and the net loss was ₹17.2-17.4 crore, a net margin of roughly -361% (Inc42, MCA-sourced financials).

Where the money comes from

• India-first customer base: Salesken’s early funding announcements (2018-2020) describe an Indian enterprise and BPO sales-team customer base, consistent with its origins in an Indian sales-training business.
• The funded pivot to the US: the November 2021 Series B was explicitly earmarked “to expand in US market,” per the company’s own PRNewswire release and coverage by Capria Ventures, one of its investors.
• No disclosed split: Salesken has not published a revenue breakdown by geography, industry vertical or channel in any source reviewed for this piece.
• The surprise: despite capital raised specifically to grow outside India, disclosed revenue went the other way — down 49.1% in the fiscal year ending March 2025 — suggesting that whatever traction the US push produced was not enough to offset softness in the base business (Inc42 financials).

The risks

• Revenue concentration in a shrinking base: revenue nearly halved in one filing year (₹10.0 crore to ₹5.1 crore) while expenses stayed at ₹22.2 crore — the mechanism of a subscription business where losing or downsizing a handful of large accounts shows up immediately in the topline (Inc42, MCA-sourced financials).
• Scale mismatch against category leaders: Salesken competes for the same conversation-intelligence budget as Gong and Mindtickle, both of which are larger, better capitalised and bundle broader sales-readiness suites — a structural disadvantage in a category where global vendors can outspend on speech-AI research and undercut a standalone product on breadth (vendor and analyst comparisons of the conversation-intelligence category).
• No priced round since 2021: the only capital raised after the Series B has come as venture debt — $9.7 million from InnoVen Capital in 2022 and $3.2 million from Stride Ventures in 2023 (Tracxn) — which adds repayment obligations rather than fresh equity cushion, a risk that compounds if losses of the FY25 scale (₹17.2-17.4 crore) persist against a smaller revenue base.

The takeaway

The lesson in Salesken is not that a good founding insight guarantees a good business; it is that the insight and the business can drift apart without anyone announcing it. Thilakan’s edge was real: years spent coaching thousands of underprivileged sales reps face to face taught her, with more precision than any market study could, what a rep gets wrong on a call and when. Encoding that into software attracted serious capital — Sequoia, Microsoft’s venture arm, a foundation with deep sector conviction — because the founder-market fit was so legible. But founder-market fit built on a decade of one-on-one coaching does not automatically transfer to a category where the buyer is a chief revenue officer comparing feature checklists against Gong and Mindtickle, priced by a procurement team rather than persuaded by a trainer in the room. The FY25 numbers suggest that gap, not a failure of the original idea, is where the company is currently stuck.
